Hi,
tl;dr: please consider applying the attached patch.
We, folks from two Debian derivatives (Tails and Freepto), are working
together to package a Tails feature for Debian: erasing memory at
shutdown/reboot. The current implementation relies on kexec.
Doing so requires to make the kexec-tools stuff a bit more flexible
wrt. being reconfigured by other packages. To start with, we have to
dynamically patch /etc/default/kexec, and the best way we've found of
doing it is to add support for a /etc/default/kexec.d/ directory,
sourced (after /etc/default/kexec) by the two initscripts shipped by
kexec-tools.
If you don't mind adding complexity to the kexec-tools package in
order to support this usecase, more patches of the same kind
will follow.
Thanks for maintaining kexec-tools in Debian!
Cheers,
